Manny Pacquiao throws punches at Mayweather on twitter

On Wednesday Pacquiao (@MannyPacquiao) tweeted "The ball will drop at midnight to usher in 2015. @FloydMayweather let's not drop the ball on fighting each other next year! #LetsMakeFistory"

A few years back this was the fight that everyone wanted to see, Pacquiao and Mayweather were on top of the boxing world but it seemed like they could not agree to terms to fight.

Mayweather wanted Olympic-style drug testing including on the day of weigh-ins to ensure both fighters were clean. Pacquiao would not agree to that, claiming the blood test would weaken him.

This is the second time Pacquiao has taken a stab at Mayweather via twitter in the past two weeks. On Dec. 16 Pacquiao tweeted ".@FloydMayweather, don't be a boxing humbug. Let's give the fans the fight they want. They have waited long enough."
